Abstract

The invention provides a blood pump and a pumping system, which relate to the field of medical appliances. The blood pump comprises a pump head and a pump body, wherein the pump body comprises a pump body shell, a motor and a driving wheel, the motor and the driving wheel are located in the pump body shell, the motor is fixedly connected with the pump body shell, the driving wheel sleeves an output shaft of the motor, and a driving permanent magnet is installed on the driving wheel; the pump head comprises a pump head shell and an impeller; one end of the pump head shell is in sealing connection with the pump body shell so as to form an impeller cavity, an inlet is formed in the other end of the pump head shell, and an outlet is formed in the side wall of the pump head shell; the impeller is installed in the impeller cavity and is close to the driving wheel; and a substrate on one end of the impeller is rotatably connected with the pump head shell, and a driven permanent magnet is fixed to a substrate, of which a blade faces towards the inlet, on the other end of the impeller. The pumping system uses the blood pump. According to the blood pump and the pumping system, the problem of blood contamination caused by direct mechanical driving of an existing blood is solved.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a blood pump and a pumping system. Background technique [0002] The heart pump is a device that partially or completely replaces the pumping function of the heart to assist in the treatment of patients with severe heart failure. It is divided into two types: internal transplantation and short-term use outside the body. Currently, the design of the motor and the pump head is usually used. [0003] The existing heart pump design can realize the basic functions of the heart pump, but because most of the motors are integrated with the pump head and directly drive, especially for the short-term use of the heart pump outside the body, it can only be discarded as a whole after use, which is relatively economical. Difference. Moreover, mechanical shaft transmission may cause axial leakage of liquid, resulting in blood contamination. [0004] Based on this, the present inve...
